                                 July 29, 2002

Dear Stockholder:

   You should have received your Proxy Statement dated July 8, 2002 regarding
the 2002 annual meeting of stockholders of Infonet Services Corporation, or
Annual Meeting, to be held on August 19, 2002 at 10:00 a.m., local time, at the
Ritz-Carlton, Marina del Rey located at 4375 Admiralty Way, Marina del Rey,
California 90292. This letter is intended to inform you of recent developments
which have arisen since the date of the Proxy Statement concerning our proposed
board composition and is accompanied by a proxy supplement and updated proxy
card, which together supplement and amend the Proxy Statement to incorporate
these recent developments. Whether or not you plan to attend the Annual Meeting
and whether or not you have already submitted a proxy card, please carefully
read the contents of this letter and the accompanying proxy supplement.

   As described more completely in the Proxy Statement, the terms of our
stockholders agreement allow each Class A stockholder that holds at least
14,950,000 shares of our Class A common stock to designate one person to serve
on our Board of Directors. Since the filing of our Proxy Statement, we have
received correspondence from Telia AB, one of our Class A stockholders that
holds at least 14,950,000 shares of Class A common stock, requesting that its
designee for election to our Board of Directors at the Annual Meeting be
changed from Morgan Ekberg (our current director and a nominee described in the
Proxy Statement) to Per-Eric Fylking (the nominee described in the enclosed
proxy supplement). We have also been informed by Mr. Ekberg that, in accordance
with Telia AB's request, he does not wish to serve as a director following
expiration of his present term.

   Our Board of Directors has considered the request of Telia AB and has
determined to withdraw its nomination of Mr. Ekberg, and instead to nominate
Mr. Fylking, for election to our Board of Directors at the Annual Meeting. In
this regard, please find enclosed a proxy supplement, which supplements the
Proxy Statement with the appropriate information regarding Mr. Fylking, and an
updated green proxy card, which lists Per-Eric Fylking as a nominee for the
Board of Directors instead of Morgan Ekberg.

   If you have already submitted a proxy card, it is important that you
carefully review the enclosed proxy supplement to understand the consequences
of failing to submit the updated green proxy card included in this mailing.
Whether or not you plan to attend the Annual Meeting, we hope that you will
complete and return the updated green proxy card in the enclosed envelope as
promptly as possible. If you attend the Annual Meeting, you may, if you wish,
withdraw your proxy and vote in person.

   We apologize for any inconvenience or confusion caused by this supplemental
mailing, and we thank you for your attention to these matters.

                                          Sincerely,

                                          /s/ Jose A. Collazo

                              PROXY SUPPLEMENT TO
                      PROXY STATEMENT DATED JULY 8, 2002

                               -----------------

                      FOR ANNUAL MEETING OF STOCKHOLDERS
                                AUGUST 19, 2002

   This Proxy Supplement supplements and amends the Proxy Statement, dated July
8, 2002, or the Proxy Statement, of Infonet Services Corporation, a Delaware
corporation, for its annual meeting of stockholders, or the Annual Meeting, to
be held on August 19, 2002 at the Ritz Carlton, Marina Del Rey located at 4375
Admiralty Way, Marina del Rey, California 90292 at 10:00 a.m., local time.

   The Proxy Statement sets forth the following proposals to be considered and
voted upon by the stockholders at the Annual Meeting:

    1. To elect nine directors to serve until the Annual Meeting of
       stockholders in the year 2003 and until their successors are duly
       elected and qualified;

    2. To ratify the appointment of Deloitte & Touche LLP as our independent
       auditor for the fiscal year ending March 28, 2003; and

    3. To transact any other business that properly comes before the meeting or
       any adjournment(s) or postponement(s) of the Annual Meeting.

   This Proxy Supplement supplements and amends information relating to
Proposal 1, the election of directors. Except as supplemented and amended
below, the Proxy Statement is unchanged. All capitalized terms used in this
Proxy Supplement and not otherwise defined shall have the meanings ascribed to
them in the Proxy Statement. This Proxy Supplement is being mailed on or about
July 29, 2002 to holders of record of our Common Shares as of the close of
business on June 27, 2002, the record date for determining the holders of
record entitled to notice and to vote at the Annual Meeting.

PROPOSAL 1: ELECTION OF DIRECTORS

   The information relating to Nominees for Director on pages 3 through 5 of
the Proxy Statement is hereby amended and supplemented by (1) removing Morgan
Ekberg as a nominee for election to the Board of Directors at the Annual
Meeting and (2) adding Per-Eric Fylking as a nominee for election to the Board
of Directors, together with his title, age, a description of his relevant
business experience and his ownership of Common Shares:



                    Name       Age              Title
                             
              Per-Eric Fylking 63  Director, Common Shares nominee


   Per-Eric Fylking retired from Telia AB, a Swedish telecommunications company
and one of our major stockholders, in 2000. From 1995 to 2000, he was the head
of mergers and acquisitions for, and a director of, Telia AB. Since his
retirement, Mr. Fylking has been engaged as an independent business consultant
by various companies, including Telia AB.



   Since the filing of our Proxy Statement we received correspondence from
Telia AB requesting that its designee for election to our Board of Directors be
changed from Mr. Ekberg to Mr. Fylking. Additionally, Mr. Ekberg has informed
us that, in accordance with Telia AB's request, he does not wish to serve as a
director following expiration of his present term. Accordingly, Mr. Fylking has
been nominated to the Board of Directors, pursuant to our stockholders
agreement, by Telia AB. Mr. Fylking has consented to be named in this Proxy
Supplement and to serve as a director if elected. Mr. Fylking has informed us
that he has no family relationships with any of the other director nominees or
with any of our executive officers. Mr. Fylking does not beneficially own any
Common Shares.

   Assuming Mr. Fylking is elected at the Annual Meeting, we anticipate that
Mr. Fylking will replace Morgan Ekberg as a member of our compensation
committee.

   With the addition of Mr. Fylking, and the removal of Mr. Ekberg, as a
director nominee, the seven Common Shares nominees for election to the Board of
Directors at the Annual Meeting are: Jose A. Collazo, Douglas C. Campbell, Eric
M. deJong, Per-Eric Fylking, Yuzo Mori, Hanspeter Quadri and Jose Manuel
Santero Munoz, and the two Class B common share nominees are Timothy P. Hartman
and Matthew J. O'Rourke.

Vote Required and Board Recommendation

   Common Shares nominees.  The seven Common Shares nominees, including Mr.
Fylking, will be elected by a favorable vote of a plurality of all Common Share
votes cast at a meeting at which a quorum is present. For purposes of the
election of the Common Shares nominees, abstentions and broker non-votes of
Common Shares will count toward calculation of a quorum but will not be counted
as votes cast and will have no effect on the results of the vote.

   Class B common share nominees.  The two Class B common share nominees will
be elected by a favorable vote of a plurality of all Class B common share votes
cast at a meeting at which a quorum is present. For purposes of the election of
the Class B common share nominees, abstentions and broker non-votes of Class B
common shares will count toward calculation of a quorum but will not be counted
as votes cast and will have no effect on the results of the vote.

   The Board unanimously recommends a vote "FOR" the election of each of the
director nominees to serve until the annual meeting of stockholders to be held
in the year 2003 and until their successors are duly elected and qualified.

YOUR VOTE

   As a result of the change in nominees, we will have two proxy cards in
existence that relate to the Annual Meeting: the white proxy card that was
originally mailed to you with the Proxy Statement (the "Original Proxy Card")
and the updated green proxy card that is attached to this Proxy Supplement (the
"Updated Proxy Card"). For purposes of determining the election of the Board of
Directors, we will treat Original Proxy Cards and Updated Proxy Cards as
follows:

       If you submit the Updated Proxy Card.  We strongly encourage you to
       submit an Updated Proxy Card, whether or not you have submitted the
       Original Proxy Card. If you have already submitted the Original Proxy
       Card, a timely submitted Updated Proxy Card will revoke your previously
       submitted proxy card and will be voted in accordance with your
       instructions on the Updated Proxy Card. If you have not previously
       submitted the Original Proxy Card, a timely submitted Updated Proxy Card
       will be voted in accordance with your instructions on the Updated Proxy
       Card. Please carefully read the Proxy Statement, the Proxy Supplement
       and the instructions on the Updated Proxy Card before submitting the
       Updated Proxy Card.


                                      2



       If you submitted an Original Proxy Card and do not submit the Updated
       Proxy Card.  If you submitted an Original Proxy Card, you are not
       required to take any action, although we strongly encourage you to
       complete and submit the enclosed Updated Proxy Card. If you do not
       return an Updated Proxy Card, your Original Proxy Card will count toward
       calculation of a quorum and will be voted in accordance with your
       instructions on all proposals except the election of Mr. Ekberg. Your
       Original Proxy Card will not be counted as a vote cast or withheld for
       the election of either Mr. Ekberg or Mr. Fylking and will have no effect
       on the results of the vote to elect Mr. Fylking.

   The Common Shares represented by all properly executed proxies returned to
us will be voted at the Annual Meeting as instructed or, if no instruction is
given, (i) all properly executed proxies on an Original Proxy Card will be
voted FOR all director nominees, except Mr. Fylking, and FOR the ratification
of the appointment of Deloitte & Touche LLP as our independent auditor for the
fiscal year ending March 28, 2003, and (ii) all properly executed proxies on an
Updated Proxy Card will be voted FOR all nine director nominees, including Mr.
Fylking, and FOR the ratification of the appointment of Deloitte & Touche LLP
as our independent auditor for the fiscal year ending March 28, 2003.

Proxy Statement. If you need another copy of the Proxy Statement, please

mailed to you at no cost. In addition, you may view copies of the Proxy

SUPPLEMENT. IF ANY REPRESENTATION OR INFORMATION IS GIVEN OR MADE, YOU MUST NOT
